The most important lessons he had taught me are that intuitive models and insights based on them are at least as important as the technical skills and that clarity and simplicity are necessary ingredients of every successful research. People who contributed to research presented in this thesis, both directly and through the inspiring discussions are Nicholas Bonesteel and Layla Hormozi from the Florida State University, Kerwin Foster from the Dillard University, David DiVincenzo from the IBM T. J. Watson Research Center and Guido Burkard and Daniel Loss from the University of Basel. I enjoyed the conversations about condensed matter physics with Professors Vladimir Dobrosavljevi´c, Pedro Schlottmann and Stephan von Molnar that kept me aware that there are many interesting faces of every problem.
